Tracking your general app usage is a handy way to see exactly what apps are sucking up your time. SlideForUsage (free) adds usage details to your app switcher. Just open up your app switcher and swipe down on the screenshot to reveal the last time you opened the app, how long you used it for, and the total amount of time you've used it since you downloaded it.
The iPhone's music app is a pretty boring white, so if you're looking for a way to spice it up a bit, ColorFlow ($1.99) is an app that colorises the stock music app with the colours from the album artwork. It's similar to iTunes' album view, and it's a great-looking little addition to the iPhone app's look.
Pluck 2 ($0.99) gives you access to your music app from Control Center. It adds a small icon to Control Center, and you can instantly pick songs and change the music. It's incredibly simple but super helpful if you don't want to unlock your device just to change a song.
Fancy ($0.99) is a subtle but surprisingly powerful tweak that colorises iOS. It doesn't sound like much, but it actually changes the look of iOS quite a bit. If you're sick of the boring old iOS colours, Fancy is worth a look.
Controllers for All
Controllers for All ($1.99) allows you to use a PS3 controller with your iOS device in place of controllers approved for Apple's MFi service. It's super easy to pair your controller with your iOS device and once you're set up you'll be gaming in no time.
Winterboard is the best way to customise the look of your iOS device, and it has only just been updated for iOS 7. If you're a fan of skinning your operating system, you won't do better than Winterboard.
Favorite Contacts 7
If you want quick access to your most-used contacts, Favorite Contacts ($1.99) puts them right in your Notification Center. The tweak uses your favourites from your phone app and puts them in your Notification Center so you can easily call, email or message them without messing around in menus.
Apptray ($1.49) adds a fourth tab to your Notification Center where you can easily launch apps. Just pick the apps you want, and they will appear there. It's something like a second-tier app launcher that nice to keep for apps you don't want to bury all the way in a folder but also don't want on your home screen.
SwipeSelection ($1.99) is a simple tweak that makes text selection in iOS less cumbersome. Instead of forcing you to hunt and peck around, SwipeSelection allows you to slide your finger across the keyboard to move the cursor around. This Pro version has all kinds of customisation options, so you can tweak your experience to your liking.
iTouchSecure ($4.99) does one thing: it matches your passwords to your fingerprints and autofills your passwords for you. So, if you want to log in to a site in Safari, you touch your finger to the TouchID sensor, and it will autofill the password. It's an easy way to ensure nobody logs in to sites when you're not around.
Notecreator (free) allows you to write notes from anywhere without opening up a whole new app. You do this by assigning NoteCreator an Activator action (like hitting the home button three times). Do the action, and NoteCreator pops up a small notification where you can quickly type a note that's saved into Notes. It's simple, but if you like taking notes and hate the fact you have to switch to another app to do so, NoteCreator solves that annoyance.
